The 1.5.0 release has introduced unconditional sets of various environment variables in src/resources/bin/config.sh. This is invoked by startHAServices in the same directory. Thus environment variables can no longer be set externally (before invoking startHAServices) to override the defaults.
This also invalidates the example at http://wiki.bigdata.com/wiki/index.php/HAJournalServer#Deployment since it is setting defaults that in fact have no effect without editing the config.sh file.
The directions at http://wiki.bigdata.com/wiki/index.php/HAJournalServer#Deployment can not be executed as given. They suggest that the ant "deploy-target" should be used and the tarball unpacked into /var/lib. However, they do not call sufficient attention to the version information in the tarball name and they specify dist/bigdata/bin/startHAServices when the unpacked path will probably be bigdata/bin/startHAServices.
The checklist for the release (and ideally CI itself) should include validation of the HA3 deployment.
Workaround: directly edit src/resources/bin/config.sh
